Though Chrome Apps use the web platform, some web features have been disabled or else are used in a
different way. Mainly this is to avoid security issues and to improve programming practices. Below
is a summary of the disabled features of the web platform and potential work-arounds:
Disabled
Work-around
alert
Use a custom lightbox/popup.
Browser chrome APIs
N/A.
confirm
Use a custom lightbox/popup.
document.cookie
Packaged app pages are not rendered on the server, so there is no need to use these.
document.close
N/A.
document.open
N/A.
document.write
Use document.createElement.
External resources
Use the webview tag for iframes. See Embed Content and Webview Tag API. Video and audio are allowed to have non-local URLs.
Flash
Use HTML5 Platform.
Form submission
Use JavaScript to process form content (listen for submit event, process data locally first before sending to server).
javascript: urls
You cannot use bookmarklets for inline javascript on anchors. Use the traditional click handler instead.
localStorage
Use IndexedDB or the Storage API (which also syncs to the cloud).
Navigation
Links open up with the system web browser. window.history and window.location are disabled.
By default, users can no longer select text like they can on a web page. To make areas of the app's text selectable, apply the CSS style, -webkit-user-select: text;.
